It looks like I'm going to be storing it with a full tank, as I have been topping up the tank a little bit at a time every time I've driven it lately, and it is nice out here today so I took it out for a drive and ended up adding $19 worth of gas to it, which ended up completely filling it up. They say it's going to be a mild December here, and are predicting no major storms, so I'm hoping to get to take it out once a week for this entire month, and each time I drive it I will top up the tank. I was more worried about having the gas lose it's octane if it was sitting for 4 months or more, but at this point now it doesn't look like the car will have to sit for anywhere near that long, so the gas should be fine. I'm hoping to get lucky and be able to drive it a few times a month for the entire winter! Then it never would really be "in storage" at all. Cars need to be exercised, I don't like the thought of it just sitting for 3-4 months straight, and I refuse to start the engine unless going to get the oil good and hot from taking it on a long drive.
